Repeat guest gift contents

We just got back from CSS and I have a question about part of our repeat guest gift. I had signed us up for the oils and candle but got a small basket of Jamaican food items instead (which I think is awesome). We received a packet of jerk seasoning, some allspice, guava jelly, and an unidentified nut/seed. We meant to ask about it while there but forgot about it until we got back and showed someone our souvenirs. It looks kind of like a pecan, but rattles when you shake it. My guess would be nutmeg, but want to be sure. Thanks for any help you can provide.
